It's fairly straightforward, sans discontinued chassis, but you could easily build the equivalent.
Chassis: Mega MA TEN Megalithic
http://www.megaarms.com/maten/receiver-sets/billet-upper-lower-sets/mts-4440-sa/
Recoil System: Armalite AR-10

I use a Chrome Silicone flat wound spring, but the Armalite complete unit is every bit as good.

I'd forego the fixed bipod though, and get a similar one with swivel capacity.

And there you have it, the closest approximation of my build I can give you. Oh, optics info, I nearly forgot!
